Application filed February 6,1914. Serial No. 817,004.

To all whom it may concern.-

Beit known that I, STEFAN ORBAN, a subject of the Austro-Hungarian Emperor, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Bearings, of which the following is a spanfication.

In some branches of the machine industry, it frequently happens, by reason of wear or because of weight, that the operatingshafting becomes displacedfrom its centered position. The displacements often do not exceed a hundredth part or even much smaller fraction of an inch, yet they may be of great importance for the proper working of the machine. Thus for instance in induction motors in which the bearings of the operating shaft are mounted in the side covers of the motor, the minutest displacements of the shaft must be avoided, in order that the air gaps between the poles of the statorand those of the rotor always remain uniform. I

modification. thereof.

My invention resides in the provision of a number of fine sheet metal strips each of,

' say .005 inches in thickness, which may be inserted at any suitable place of the bearing, either directly between the bearing box and hanger, or between the hanger and the part to which it is fixed or any other convenient place. To effect the readjustment of the displaced shaft, one, two or more strips, according to the. extent of displacement, are

removed from one place and addedto the diametrically opposite place, thereby raising the shaft to its central DOSliZlOIL Thus for instance in Fig. l a number of sem1-circularly curved metal strips d, (1 05- each of a thickness of a small fraction of an inch are shown arranged in an annular central groove 6 of the bearing box 6 and enveloped by a split ring 0 adapted to bear with its outer circumference against the walls of the hanger or stationary part a-. There are two uniform sets of suchstrips, one set surrounding the upper and the other the lower half of the box. If the box has become displaced from its central position owing to weight of the shafting or for any other reason, one of the metal strips of the upper set (or more if necessary) is removed from and added to the lower set. Thereby the bearing box and consequently the shaft are raised to central position. If the hearing is a swivel bearing, the outer circumference of the ring 0 may be cylindrically curved, as indicated by dotted lines, to engage a correspondingly curved socket in the hanger or part a.

In Fig. 2 the sets of metal strips (1, d are arranged between the hanger a and the split ring 0. The swivel in this case is formed between the box and inner surface of the ring, as at 5 In Fig. 3 the same arrangement is shown, as in Fig. 1, excepting that instead of a single central support of'box b in the hanger there are either two lateral supports or lateral and central supports. In this case the sets of metal strips are arranged in each support in the same manner, as in Fig. 1.

In Fig. 5 the hanger carrying the bear ing is represented as side or end-cover f of a cylinder 7 of, say an electric motor. The metal strips d, (F, (Z are shown arranged between an inwardly extending flange f and the end wall 9 of the cylinder g. The hanger or part Z) is shown as integral piece of the cover f. I

In Fig. 6 the part w is not integral with the cover, but is fixed to it by bolts it passing through slots f? in the cover 7". Illtllls case the metal strips d, d ranged between the cover as shown.

Of course there may be various other ways may be ar- 7 and the part a of arranging the metal strips, without dcparting from the spirit of my invention,

and I therefore do not restrict myself to the arrangements shown and described,

" Whetlchim and I 5 metal strips or shims-interpose 3 saidvbo'x and frame and a split ring carrying v said metal strips or shims.
